Overview
The BC856ALT3G is a PNP silicon general-purpose transistor manufactured by onsemi. It operates with a collector-emitter voltage of -65 V and a continuous collector current of -100 mA dc. The device utilizes an SOT-23 (TO-236AB) plastic surface-mount package. Electrical characteristics include a minimum DC current gain of 125 at -10 mA, a transition frequency of 100 MHz, and a total power dissipation of 225 mW on an FR-5 board.
Feature Summary
- Designed for general-purpose switching and audio frequency amplifier applications
- Manufactured using lead-free, halogen-free, and brominated flame retardant-free processes compliant with RoHS standards
- Capable of automatic insertion into thick and thin-film circuits
Applications
- General-purpose switching circuits
- Audio frequency amplification stages
- Automatic insertion in thick and thin-film circuit assemblies
Procurement Notes
Verify the specific ordering suffix to confirm the reel quantity and tape specifications required for your assembly line. Confirm that the device marking matches the datasheet diagram for the selected variant. Ensure compliance with automotive site requirements if AEC-Q101 qualification is necessary for the application.
Selection Notes
Select this component when a low-voltage PNP switch or amplifier is needed in a compact surface-mount form factor. Consider the thermal resistance and safe operating area curves for high-power pulse applications. Verify that the base-emitter saturation voltage meets the drive requirements of the preceding logic stage.
Part Context
This part belongs to the BC856ALT1G series, which includes variants with different DC current gain ranges such as BC857 and BC858. All members share the same physical package and maximum ratings but are binned for specific hFE performance levels to suit various amplification needs.
Replacement Considerations
Direct substitutes within the same family include BC856BLT3G and BC856ALT1G. Cross-manufacturer equivalents like the NXP BC856W require verification of pinout compatibility and electrical parameter margins.
